Air pollution, not diet, shows the strongest link to poorer concentration in schoolgirls

This cross-sectional study of 300 school-aged girls in Tehran found that higher air pollution exposure was consistently associated with poorer concentration, while dietary antioxidant capacity showed weaker, model-dependent links to attention. No significant associations or interactions were observed for short-term memory, highlighting pollution exposure as the dominant factor influencing attentional performance.
